Solar plastic sheeting power generation

What are ultralight fabric solar cells?

Credit: Melanie Gonick, MIT MIT engineers have developed ultralight fabric solar cells that can quickly and easily turn any surface into a power source. These durable, flexible solar cells, which are much thinner than a human hair, are glued to a strong, lightweight fabric, making them easy to install on a fixed surface.

What is photovoltaic (PV) technology?

Solar energy is the most-abundant renewable energy-resource and among the various solar techniques, photovoltaic (PV) technology has emerged as a promising and cost-effective approach .

Why do plastic solar cells use MEH-PPV?

The early plastic solar cells utilized MEH-PPV, which was designed with asymmetric and racemic 2-ethylhexyl side-chains explicitly to make the polymer more glassy (i.e. homogeneous) in the solid state as well as to improve the solubility.

How are solar panels made?

They are one-hundredth the weight of conventional solar panels, generate 18 times more power-per-kilogram, and are made from semiconducting inks using printing processes that can be scaled in the future to large-area manufacturing. Because they are so thin and lightweight, these solar cells can be laminated onto many different surfaces.

How are solar cells made?

To produce the solar cells, they use nanomaterials that are in the form of a printable electronic ink. Working in the MIT.nano clean room, they coat the solar cell structure using a slot-die coater, which deposits layers of the electronic materials onto a prepared, releasable substrate that is only 3 microns thick.

How efficient are all-polymer solar cells?

In the 18 August issue of Advanced Materials, researchers led by Alex Jen, a materials scientist at the University of Hong Kong, reported all-polymer solar cells that had an efficiency of 17% and retained 90% of their efficiency under accelerated aging tests. “That is quite notable,” says Bao, whose team also works on all-polymer cells.
